Project Apple

Posted by matthew65536 Jun 21, 2016

I have an idea for a project, the main use of this computer will be normal pc usage, such as Internet browsing, Retro gaming (which seems to be the most famous use of the Raspberry pi), and other things. So, your probably wondering, why is it named the Apple pi? well, i named it the Apple pi, because i want to use the case of on Apple Macintosh Classic, or any of the older one-piece Macintosh computers, i was hoping to have it to where it can be turned off and on with a switch also can be powered with a laptop battery. What i need help with is finding the parts to make it work, because i know the Raspberry pi is powered with 5V, i need help finding the right parts for it, all i need is a 9" LCD screen, i was hoping it can use the built in screen adapter, so i can use HDMI to plug in another monitor or a TV, i also want to make sure it is still portable, or... as portable as a Macintosh was. I would appreciate it if i can get some help on finding the parts like the battery and the LCD screen.

Hello,

Just finished modding my new Pi3. Before modding I gave it a stress test for 20 mins using Sysbench prime calucation. I was getting 78~81C on ARM CPU. So I decided to do something about it before the hot summer arrives.

The codes I used for the stress test... you can download sysbench by typying "sudo apt-get install sysbench"

I dug out some Pentium II heat sink and started hacking away using dremel. I tried to mod as large piece of heatsink as possible in an slim aftermarket Pi case;  I had to sand for 2 hours using 180 grid sand paper to get the heatsink down to perfect size.

I used Laird thermal pad (those used on GTX 980Ti GDDR5 rams) for TIM between heatsink and CPU. Larid thermal pads are  petty expensive little sucker at 1USD a pop...since they have 5W/m.k. thermal conductivity it's all good. Also used some electrical tape for protecting those taller IC components around the chips. Note that I didn't use thermal paste because I want to create more distance between the heatsink and IC components on board.

I slapped on the heatsink on using a little bit of glue gun make to make sure heat sink is firmly installed on the board. (Press down hard while the glue cures). I used glue gun because it makes it easier to remove in the future.

I dremel a perfect round hole on top of the case for a 12V 4cm Fan, which I will be running at 5V. This makes the fan so quiet I have to stick my ear to it to hear it. Put some shinny fan grill to make it good look

For the DDR2 ram, I used Silicon cooling pad to spread the heat and transfer some heat the case (every little bit helps!). The pad was too thick so I sliced it in half, but still thick enough to touch the bottom of the case with some pressure.

Putting everything together and run the same stress test for 30 mins~~~

Check out those sexy exhaust ports in the back~

The result I got was 49~51C!!! Bang! feels good for three hours of work!

Musicbox Raspberry Pi 3

Posted by accel79 Jun 8, 2016

Background

I have been upgrading my old Harman Kardon AVR 630, first i installed an HDMI Switch to upgrade the connectivity. Now i want to installed a Raspberry Pi 3 with Pi Musicbox to upgrade my receiver with streaming services like: Spotify, tunein, google music, soundcloud and podcast and also the capability of play FLAC files from network and locally.

 

Hardware Components

 

Installation

After you put all the hardware together it's time to  work with the software.

 

First download the Pi MusicBox image from the Pi MusicBox website and install it on an SD card. I used RPi-SD Card Builder for Mac, If you’re using Windows it sounds like Win32DiskImager is the thing to use.

Unfortunately there's not official support from Pi Musicbox for Raspberry Pi 3 yet, if you put this SD card into your RPi3 all you’ll get is the rainbow boot screen. You’ll need to copy a few files from a more recent raspbian image to get it to work.

Here comes the trick:

The most recent versions of Raspbian Jessie do not work with this technique, so you’ll specifically need the 2016-03-18 version available here. Unzip that file and mount it, on OS X you can use the built in DiskImageMounter.

Once you’ve mounted that image you’ll just need to copy a few files to your SD card, overwriting the files on the PiMusicBox image. Those files are: All the .dtb, .bin, .dat and .elf files.

Overwrite those files on your Pi MusicBox SD card and you should now be able to boot up, after the first attempt the Pi will reboot one time to fix the changes in the files and that will be all, You will have the Pi MusicBox working in the Raspberry Pi 3.

Here some screenshot from Iphone and Ipad interface

Next step will be upgrade it with a HiFiBerry DAC+ for a huge improvement in audio quality

Thanks to TechEnvy and Christoph Buenger for their great guides.
